Relation of Key ways of input and output shafts are organized as following.
Index Types
Datum Position of RI Series
Key position in the timing chart
α･･･ Cam Index Angle (°), β･･･ Dwell Angele (°), S･･･ Number of Stops
Datum Position of Input Shaft
The keyway position in the timing chart is datum position of its input shaft. As the right diagram, it is set up in intermediate position of its dwelling interval. Also, if the mark-off line with keyless goes by, a mark-off line is incised perpendicularly from the center of the shaft end face as shown in the right diagram.
Datum Position of Output Shaft
For datum position of the output shaft for standard specifications, please refer to the dimensinal drawings of each series.
● Shaft Type: Direction of the keyway ● Flange Type: Position of the mounting tapped hole ● If there is no keyway and tapped hole, a mark-off line is incised perpendicularly from the center of the shaft end face as a keyway position or a datum tapped hole in the dimensional drawing.Oscillating Types

Datum Position of Input Shaft
The keyway position in the timing chart is datum position of its input shaft. As the right diagram, it is set up in intermediate position of its dwelling interval. Also, if the mark-off line with keyless goes by, a mark-off line is incised perpendicularly from the center of the shaft end face as shown in the right diagram.
Datum Position of Output Shaft
For datum position of the output shaft for standard specifications, please refer to the dimensinal drawings of its respective series.
